The SITRA CUBE is available in 3 colour options, white anthracite and rust effect.
There are two lamps required to power this up / down light. It has a clean square
style for the modern house. Energy efficient using the latest 9w circular fluorescent
lamp technology for long life and low energy cost's. Easy clean flat glass
lens with 4 retaining screws.
The light distribution is a wide beam projecting upwards and downwards and suitable
for an entrance porch or perimeter wall lighting to illuminate a pathway below and
the main façade of the building. Very low glare due to the flat plate design.
The anthracite and white can also be matched to the THEOS CL ceiling mounted luminaries
as a set.code 232541 white and code 232545 anthracite.

Please ensure that all exterior installations are carried out by a NIE EIC certified
electrical contractor and that all cable joints are 100% water tight.

Installation

Care must be taken when installing exterior lighting products especially those that
are ground mounted. All the products are sold and tested fit for purpose and the
IP rating is set according to the design and purpose of the luminaire, more details
on IP ratings can be found under design ideas section. The weakest point is generally
the installation of the product where adequate drainage has not been made for ground
buried lights or poor cable joints have been made which are not 100% water tight
and will allow for water penetration. There are a number of waterproof enclosures
available on this site along with heat shrink cable joint kits and resin gel packs
to fill the junction boxes to make a watertight enclosure. Where possible try and
keep all joints and transformers above ground, however if this is not possible there
are potted burial kits available.

Lamp colour ( Kelvins )

Lamp colour is determined by the Kelvins and a lamp which is 2700 kelvin
is classed as warm white and sympathetic to skin tones and warm brickwork. A kelvin
of 6500k is in the blueish white spectrum and works well against a white background
and will appear brighter to the naked eye than the warm colour spectrum.

Light output ( Lumen's )

All lamps have a lumen number and the higher the lumen number the
brighter the lamp,
however colour of the lamp (kelvins ) also comes in to play here as a
whiter lamp
at 6,000 kelvins and above would always appear brighter to the naked
eye than a warmer
colour lamp at the 2,700 kelvins light spectrum even if it has the
same lumen output.
A halogen 150w R7 lamp that is used in a standard garden security
flood light would
produce around 2,300 lumen's and a 26w compact fluorescent would
produce around 1,800 lumen's. Placing lights closer to the item to be
illuminated is a good way of
using a lower lumen lamp rather than trying to flood light a big
area.

Environmental impact

Care should be taken for local wildlife, insects, and general light
pollution,
this means the warmer colour spectrum ( 2, 700 kelvin ) does not
interfere with insects and general
wildlife as much as the blue spectrum ( 4,000 kelvin and above ).
Cool white colours can disrupt insects and wildlife's normal
night time activity. This also applies to bats where a anti glare
light fitting works
better as well as reducing overall light pollution in the area.
